Aluminium Translation stages 7T175-100 and 7T175-150 using own integrated driving screws for very precise and long travel translation. The screw has a micrometric scale (on the body and knob). The pitch of the screw is 0.5 mm. Custom pitch and gears are available on request. Translation Stages 7T175-100(-150) are preloaded by a collar of our original design on the screw, rendering an increased load capacity, stability, and reduced backlash. Translation stages have a number of M6 and M4 clearance holes on the platforms, see the whole great amount of holes on the stages surface in drawings. XY configuration assembled directly using M6x10 screws, no additional base plates required. For more convenient mounting to optical table or similar surface we offer Base Plate 3UBP175. For Z-axis assembly we offer Angle Bracket 2AB175. Motorized version of this stage 8MT175 series.
